Previously the "terraform state ..." subcommands were the only way to
perform various manipulations of the state, but in recent Terraform
versions we have replaced these with better options.
Since these pages seem to already have pretty good search engine
optimization for the use-cases they are describing, we'll prioritize
mentioning the new approaches and only mention the now-deprecated or
de-emphasized features as a secondary approach.
Specifically:
- Describe the -replace=... planning option in preference to
"terraform taint", and present taint as primarily a mechanism for
Terraform to use itself, as opposed to something end-users should
typically use directly.
- Introduce the config-based refactoring features before describing
"terraform state mv".
The older features here are still applicable in some situations and are
required for those still using older versions of Terraform, so we will
retain the information about them for now while aiming to be clearer in
each case about which is our preferred, modern approach.
Apologies for not creating an issue first but it seemed like a simple docs change.
`apt install terraform` requires the `apt update` before terraform can be installed.
The HashiCorp APT server supports several distro releases that were not in this list,
leading to a false impression that they aren't supported.
Note, Ubuntu has a new release twice a year, so periodic maintenance
is needed here.
We introduced this experiment to gather feedback, and the feedback we saw
led to us deciding to do another round of design work before we move
forward with something to meet this use-case.
In addition to being experimental, this has only been included in alpha
releases so far, and so on both counts it is not protected by the
Terraform v1.0 Compatibility Promises.
We're aware of several quirks of this command's current design, which
result from some existing architectural limitations that we can't address
immediately.
However, we do still want to make this command available in its current
capacity as an incremental improvement, so as a compromise we'll document
it as experimental. Our intent here is to exclude it from the
Terraform 1.0 Compatibility Promises so that we can have the space to
continue to improve the design as other parts of the overall Terraform
system gain new capabilities.
We don't currently have any concrete plan for this command to be
stabilized and subject to compatibility promises. That decision will
follow from ongoing discussions with other teams whose systems may need to
change in order to support the final design of "terraform add".
